To search by structure, left click in the box below to display the chemdraw toolbar. Then, draw the chemical structure of interest in the box using the toolbar. When your structure is complete, click “Search by Name” or “Search by SMILES” to generate the product name or SMILES respectively. This feature will search within the Gelest product database for matching chemical names or SMILES. Note: In cases where Gelest uses alternate chemical names, it may be necessary to search for the product of interest by its CAS#.

Specialty Polyethers & Olefins

PEGylation, the formation of a conjugate of a protein, peptide, drug or other bioactive material by linking it with one or more PEG chains, in many instances imparts desirable properties to a biomolecule: increased solubility, resistance to metabolic degradation and reduced immunogenicity. Gelest has introduced a unique range of dual-function poly(ethylene glycol) (PEG) reagents that enable new approaches to PEGylation for bioconjugates, reduction of surface biofouling and formation of polymerizeable vesicles for drug transport. More information can be found in the Gelest Reactive Polyethers brochure.

Olefins are important intermediates in the production of organosilanes, silicones and other metal-organic materials. In order to support internal production requirements Gelest maintains inventory of a variety of olefins and specialty unsaturated monomers. Even though the olefin products are not part of the standard product line and technical literature is not available, Gelest offers them for sale in excess to its internal requirement. Please inquire for bulk or commercial quantities. More information can be found in the Gelest Specialty Olefins brochure.
